Description

Technical Field

[0001] This utility model relates to the field of power distribution product technology, specifically to a power distribution box. Background Technology

[0002] Typically, cables are laid out inside facilities such as construction sites, factories, and ships. To ensure the aesthetics of cable routing and prevent inconvenience caused by messy cable arrangement, cable trays are installed inside these facilities, where multiple cables are bundled and fixed.

[0003] In existing technologies, cable trays consist of horizontally arranged horizontal and vertical cable trays. Since the horizontal cable trays are typically installed near the ceiling, high off the ground, the cable routing direction needs to be reversed to the vertical cable trays to connect the horizontally arranged cables to the distribution box near the ground. When installing the vertical cable trays with the distribution box, the left and right frames of the vertical cable tray are fixedly connected to the left and right sides of the distribution box. However, when the lateral dimensions of the distribution box (i.e., the distance between the left and right sides) are narrow, the connection between the vertical cable tray and the distribution box, as well as the cable routing, presents installation difficulties. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a distribution box to solve the problem of installation difficulties caused by the fact that the lateral dimensions of the existing distribution box are difficult to match with the dimensions between the left and right frames of the vertical wire trays in different installation sites.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a distribution box, including a distribution box body, and further comprising:

[0007] A pair of connecting brackets, one side of each connecting bracket is fixedly installed on the back of the distribution box body, and the other side of each connecting bracket has a mounting groove for accommodating one end of the frame of the vertical wire tray. Screw holes are respectively opened at the upper and lower ends of the mounting groove near the inner side wall of the distribution box body, and connecting holes are respectively opened at the upper and lower ends of each connecting bracket.

[0008] A pair of movable rods, each movable rod having a movable end and a limiting end arranged opposite to each other. The movable end has a plurality of first locking holes spaced apart along the length direction of the movable rod, and the limiting end has a second locking hole. The outer side of the limiting end has a limiting block, the outer dimensions of which are larger than the opening size of the connecting hole. The movable ends of the pair of movable rods are respectively horizontally inserted into the connecting hole of the other connecting bracket through the connecting hole of the connecting bracket and extend outward.

[0009] A pair of connecting bolts, one end of which enters the screw hole through the first locking hole and the second locking hole respectively.

[0010] Furthermore, the upper and lower ends of the connecting bracket are respectively fixed to the back of the distribution box body by bolts.

[0011] Furthermore, horizontal through grooves are provided at the top and bottom ends of the back of the distribution box body.

[0012] Furthermore, the opening size of the mounting slot is larger than the outer dimensions of one end of the frame of the vertical cable tray.

[0013] Furthermore, the inner surface of the connecting bracket has reinforcing ribs.

[0014] The beneficial effects of this utility model are as follows:

[0015] By using the aforementioned distribution box, the back of the distribution box body is fixedly installed at one end of a pair of connecting brackets, and the other end of the connecting brackets is snapped into the frame of the vertical wire tray. A movable rod is horizontally connected to the pair of connecting brackets. The movable rod can be flexibly adjusted in its lateral installation length within the pair of connecting brackets to match the width between the two side frames of the vertical wire tray. Specifically, the first and second locking holes at both ends of the movable rod are adjusted to correspond to the positions of the connecting holes on the pair of connecting brackets. Connecting bolts are inserted into the first and second locking holes, with one end of the bolt extending into the screw hole and contacting the end face of the frame of the vertical wire tray, thus pressing the frame tightly into the connecting brackets. In this solution, by installing a movable rod between the pair of connecting brackets and adjusting its installation length to match the spacing between the two frames on the vertical wire tray at the construction site, the installation difficulty caused by the existing distribution box's lateral dimensions being difficult to match with the dimensions between the left and right frames of the vertical wire tray at different installation sites is solved.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] See appendix Figure 1 To be continued Figure 3 As shown, this embodiment provides a distribution box 10, including a distribution box body 100, a pair of connecting brackets 200, a pair of movable rods 400 and a pair of connecting bolts 500.

[0031] The distribution box body 100 uses a common distribution box structure found in the market. It includes a flip-open or closable door cover 101, and components and accessories (such as circuit breakers, contactors, electrical instruments, copper busbars, busbars, etc.) are installed inside the distribution box body 100. In addition, to facilitate users to directly observe the usage of the components and accessories inside the distribution box body 100, the upper part of the door cover 101 is provided with a transparent observation port 102, such as a transparent observation port 102 made of acrylic material.

[0032] A pair of connecting brackets 200 are symmetrically arranged on the back of the distribution box body 100. The pair of connecting brackets 200 are used to be fixedly connected to the outer edges of the left and right sides of the back of the distribution box body 100. Specifically, one end of the connecting bracket 200 is fixedly installed on the back of the distribution box body 100 by bolts.

[0033] See attached document Figure 3As shown, a groove 103 is provided on the back of the distribution box body 100 corresponding to the area on the connecting bracket 200 where the aforementioned bolts are installed. The groove 103 extends horizontally from one side of the back of the distribution box body 100 to the opposite side. When the connecting bracket 200 is fixedly installed on the back of the distribution box body 100, the end of the bolt passes through the mounting hole 201 on the connecting bracket 200 and extends into the groove 103, where it is threadedly connected to the threaded connection hole 204 provided in the groove 103. The groove 103 allows the operator to better control the bolt insertion position when connecting the connecting bracket 200 to the back of the distribution box body 100 with bolts, thus improving bolt installation efficiency.

[0034] See attached document Figure 3 As shown, in order to improve the strength of the connecting bracket 200, the inner side of the connecting bracket 200 has reinforcing ribs 205.

[0035] See attached document Figure 1 Appendix Figure 2 and appendix Figure 4 As shown, the other end of the connecting bracket 200 has a mounting groove 202, which is used to accommodate one end of the frame of the vertical wire tray 300. Screw holes 203 are respectively provided at the upper and lower ends of the mounting groove 202 near the inner sidewall of the distribution box body 100. The direction of the screw holes 203 is perpendicular to the back of the distribution box body 100, that is, parallel to the installation direction of the bolts. For ease of installation, the opening size of the mounting groove 202 is larger than the outer dimensions of one end of the frame of the vertical wire tray 300.

[0036] Continue to refer to the appendix Figure 1 Appendix Figure 2 and appendix Figure 4 As shown, in order to facilitate the installation of a pair of movable rods 400 on the upper end of a pair of connecting brackets 200, each connecting bracket 200 has a connecting hole 204 at its upper and lower ends. The connecting hole 204 is opened in a horizontal direction. The movable rod 400 passes horizontally through the connecting hole 204 and is installed horizontally between the pair of connecting brackets 200. The reason for installing the movable rod 400 horizontally at the upper and lower ends of the pair of connecting brackets 200 is to ensure the connection stability between the pair of connecting brackets 200.

[0037] See attached document Figure 5As shown, the movable rod 400 is approximately rod-shaped. The movable rod 400 has a movable end 401 and a limiting end 402 that are arranged opposite to each other. The movable end 401 has a plurality of first locking holes 405 spaced apart along the length direction of the movable rod 400. The limiting end 402 has a second locking hole 404. The outer side of the limiting end 402 has a limiting block 403. The outer dimensions of the limiting block 403 are larger than the opening size of the connecting hole 204. The movable ends 401 of a pair of movable rods 400 are respectively horizontally inserted into the connecting hole 204 of one connecting bracket 200 and extend outward. It is understandable that by providing a limiting block 403 with an outer dimension larger than the opening size of the connecting hole 204 on the outer side of the limiting end 402, the movable end 401 of the movable rod 400 is horizontally inserted into the connecting hole 204 of the opposite connecting bracket 200 and extends outward. During this process, the limiting end 402 of the movable rod 400 will not pass through the connecting hole 204 of the connecting bracket 200. The limiting hole restricts the limiting block 403 from continuing to move. This ensures that when the movable rod 400 is installed with the connecting bracket 200, the movable rod 400 will not directly pass through the connecting hole 204 on the connecting bracket 200, thus avoiding the need for reinstallation and reconnection due to the movable rod 400 directly passing through the connecting hole 204.

[0038] See attached document Figure 1 To be continued Figure 5 As shown, when installing the connecting bracket 200 with the frame of the distribution box body 100 and the wire tray 300, firstly, the mounting groove 202 at one end of one connecting bracket 200 is engaged with one side frame of the wire tray 300. Then, the movable ends 401 of a pair of movable rods 400 are respectively inserted into the connecting holes 204 at the upper and lower ends of one connecting bracket 200, so that the movable ends 401 pass through the corresponding connecting holes 204 of the other connecting bracket 200. Then, the mounting groove 202 of the other connecting bracket 200 is engaged with... The other side frame of the cable tray 300 engages with the cable tray 300. Finally, one end of a connecting bolt 500 passes through the second locking hole 404 and enters the screw hole 203 in the mounting groove 202 on one side, causing the end of the connecting bolt 500 to contact the end face of the vertical cable tray 300 frame. As the connecting bolt 500 continues to be screwed in, the end of the connecting bolt 500 pushes the outer wall of the mounting groove 202 against the frame, thus pressing the frame tightly into the mounting groove 202 of the connecting bracket 200 (see attached diagram). Figure 6(As shown); Similarly, another connecting bolt 500 is inserted into the first locking hole 405 at one end of the movable end 401 of the movable rod 400, where it coincides with the screw hole 203 on the other side of the connecting bracket 200, so that the end of the other connecting bolt 500 abuts against the bottom end of the other side frame of the vertical wire tray 300, and the frame is pressed into the mounting groove 202 of the connecting bracket 200 by the end of the connecting bolt 500.

[0039] During the installation process described above, the movable rod 400 can be flexibly adjusted to adjust its lateral installation length on a pair of connecting brackets 200 to match the width between the two side frames of the vertical wire tray 300. Specifically, the first locking hole 405 and the second locking hole 404 at both ends of the movable rod 400 are adjusted to correspond to the positions of the connecting holes 204 on the pair of connecting brackets 200. By installing the movable rod 400 between the pair of connecting brackets 200 and adjusting its installation length, the spacing between the pair of frames on the vertical wire tray 300 at the construction site can be matched. This solves the problem of installation difficulties caused by the difficulty in matching the lateral dimensions of existing distribution boxes with the dimensions between the left and right frames of the vertical wire tray 300 at different installation sites.

[0040] After the frame of the connecting bracket 200 and the vertical wire tray 300 is connected, the other end of the connecting bracket 200 is fixed to the back of the distribution box body 100 by bolts, thereby completing the installation between the distribution box body 100 and the vertical wire tray 300.

[0041] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
